Abstract
The invention discloses a four-wheel driving system controlled by four-wheel independent motors. According to the major technical scheme, four wheels of an electric vehicle are driven independently by using one motor respectively; the torques of the motors for driving each wheel are controlled and allocated by a central controller. According to the four-wheel driving system driven by the independent motors, a differential mechanism and a differential lock are not required to perform torque allocation of front and back wheels and differential speed of the inner and outer wheels during turning, and the rotating speeds of all wheels are implemented through the central controller.
Description
Technical field:
The present invention relates to a kind of four-wheel drive system of electronlmobil, especially by the battery-driven car four-wheel drive system using independently motor to drive to electronlmobil four wheels.
Background technology:
Being becoming tight global energy day, ecology environment goes from bad to worse, and under the background that particularly energy-saving and emission-reduction pressure is increasingly serious in recent years, pure electric automobile industry realizes the important selection of energy-conserving and environment-protective, development low-carbon economy beyond doubt.Pure electric automobile becomes because it has the advantages such as zero-emission, low noise, efficiency are high, diversified the low-carbon environment-friendly industry falling over each other to develop in various countries, and especially the countries and regions such as the U.S., Europe, Japan, China are all regarded as one of emerging strategic industries first developed.
According to the plan of the relevant pure electric automobile launch that global Ge great car company issues in succession, estimate that before and after the year two thousand twenty, the whole world will welcome a climax of pure electric automobile industrialized development.Multinational and regional priority puts into effect a series of policies and regulations file, drops into substantial contribution, advances the research and development of pure electric automobile technology, helps pure electric automobile industry development.
In pure electric automobile application, centralized (single motor) driving and distributing (many motors) can be divided into drive two large classes according to power system topological structure.The electronlmobil of centralized driving structurally with orthodox car relatively, still adopt power drive by the transmission of torque of central motor on drive wheel.The electronlmobil that distributing drives equips multiple motor, according to the position of motor, is divided into again wheel motor to drive and In-wheel motor driving.It is combined with wheel hub by motor that hub motor for electric automobile drives, direct drive of wheel, wheel hub motor many employings permanent magnetic brushless type.Michielin company began one's study from 2008 its driving wheel system, was integrated with a compact suspension system in wheel.Have two motors in driving wheel system, a motor can provide the continuous power of 30kW to drive or brake, and another motor is used for doing Active suspension control.Active suspension system can stabilizing cars travel time jolt.Siemens VDO proposes " drive-by-wire " concept and started eCorner project in 2006, develop Electric Corner Modules (ECM) by tire, wheel hub, brake, turn to, suspension, motor and cooling system combine, and replaces the suspension system of orthodox car.Target reduces vehicle weight, improves fuel economy.Protean Electric company develops the liquid cooling wheel hub motor system of integrated inverse device, this In-wheel motor driving system at some pure electronic and mixed power electric cars (as Volvo C30, Ford F150 etc.) upper test, have accumulated the racing track more than 3 years and road test result.
Summary of the invention:
The present invention is the four-wheel drive system that a kind of four-wheel individual motor controls, its technical scheme is separately use a motor to drive four of battery-driven car wheels, motor drives the moment of torsion of each wheel to be undertaken controlling and distributing by central controller, when the vehicle is turning, central controller adjusts the rotating speed of outboard wheels in vehicle automatically according to the feedback of the rotation of bearing circle and wheel and road surface contact friction force, when the some wheels of appearance run out of steam skidding, central controller exports according to the moment of torsion of feedback adjustment corresponding motor, carries out the braking of corresponding wheel.
Use wheel hub motor separate connection four wheels.
Central controller is the four-way controller based on micro controller system and CPLD to the control of wheel.
This four-wheel drive system of wheel being carried out to individual motor control can realize the effect of differential for vehicles, differential locking-device and ESP by central controller itself.
Beneficial effect:
It is a kind of novel vehicle driving patterns that the motor of automobile drives, the structure of design vehicle should be carried out with new pattern, new thinking, traditional fuel engines structure control is complicated, manufacturing cost is high, a driving engine can not be independently set to each wheel, but for electronlmobil, independently motor is only needed to drive wheel, the cost of motor manufactures the cost of a set of four-wheel drive system far below orthodox car, and by simply realizing based on micro controller system and programmable logic device (PLD), very high economy can be had for the control of motor.
Accompanying drawing illustrates:
Fig. 1 is the structural representation that four-wheel individual motor controls four-wheel drive system.
Detailed description of the invention:
For better the present invention being described, be convenient to understand technical scheme of the present invention, typical but non-limiting embodiment of the present invention is as follows.
Be connected with motor 1 by the near front wheel, off front wheel is connected with motor 2, and left rear wheel is connected with motor 3, and off hind wheel is connected with motor 4, and each wheel of such battery-driven car uses a motor to drive independently.
By central controller, four motors are independently controlled, thus drive corresponding wheel to carry out advancing and braking.
When the vehicle is turning, central controller adjusts the rotating speed of outboard wheels in vehicle automatically according to the feedback of the rotation of bearing circle and wheel and road surface contact friction force, when the some wheels of appearance run out of steam skidding, central controller exports according to the moment of torsion of feedback adjustment corresponding motor, carry out the braking of corresponding wheel, achieve the effect of differential for vehicles, differential locking-device and ESP.
Applicant states, above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made, all should be considered as belonging to protection scope of the present invention.
